I had to purchase a new set of wheels due to balancing and alignment issues I developed after bending both American Racing aluminum wheels on the trail, while the Jeep was heavily loaded.
Hub caps come with the D909 wheels which cannot be over-torqued, or the allen bolts can be damaged. The rim edges can be scratched on the trail, but a Black Rock representative told me that you simply add touch-up paint to the damaged sections, and they will look as good as new.
The 1/4" dimples need to be cleaned with a Q-tip swab periodically - especially if your Jeep hits the mud.
These wheels make any Jeep look better than stock. They run true, are lightweight, and inexpensive. No, I don't work for Black Rock - just a satisfied customer.
A 255/75 r17 measures out to - 32.06" diameter x 10.8" wide. A 17x8" rim is a good size when traveling on the road, but when aired down, could be vulnerable to losing a bead. Just like, if I was running a 15x10" wheel with my 12.5" wide tires that I run.
FWIW, the new Interco wheel has a special bead retention system that is DOT compliant, weigh less than bead locked wheels, and although come in a 17x9" size, would probably hold the bead better than a 17x8" design w/o a bead lock.
